Temporomandibular joint disorders (TMJD) and dentofacial deformities often co-exist. One could be the cause or effect of the other. Orthognathic surgeries performed without management of active TMJD can risk unfavorable outcomes. Accurate diagnosis of TMJD and management is critical in patients with dentofacial deformities. Published studies show a significant number of OMS do not perform TMJ surgeries as part of their practice that could result in patient being treated with only orthognathic surgery or being referred to another practitioner. Traditionally, these conditions were treated in separate surgical encounters that increased morbidity and risks to patients. Recent data supports combining these treatments in appropriate patients when indicated could reduce morbidity of two procedures or risks from an untreated TMJD. Technological advances such as virtual surgical planning/3D printing have created ways for these surgeries to be done with precision, reduced surgical time and good outcomes. Combining these surgeries improves quality of care and patient convenience while decreasing risk from second general anesthesia. Combined surgeries are not done as commonly as conventional orthognathic surgeries, and OMS trainees and practitioners may not be familiar with the intricacies. This course intends to present indications, contraindications, planning, technique, risks and benefits related to these combined TMJ-orthognathic surgeries.
Learning Objectives:
At the conclusion of this presentation, participants should be able to:
Discuss indications and identify patient who could benefit from a combined TMJ-orthognathic surgery.
Describe the steps in planning/work-up for a combined surgery.
Explain the differences between a traditional orthognathic surgery and a combined surgery.
